IMPROVEMENT IN TH I LL-COUPLINGS.

Speciiication forming part of Letters Patent No. 198,074, dated December11, 1877 application filed May 25,1877.

To all whom t may concern: v

Be it known that I, WILLIAM H. BRAGE, of Nunda, in the county ofLivingston and State of New York, have invented certain new and usefulImprovements in Thill-Gouplings; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

The nature of my invention consists in the construction and arrangementof a thill-coup ling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I -will now proceed to describe itsconstruction and operation, referring tothe annexed drawing, in which-Figure l is a central vertical section, and Figs. 2 and are detailviews, of my invention. i

Arepresents the axle, with clip B around the same, said clip having onits front two fbrwardly-projecting parallel ears, C C, with a round pin,D, connecting the same, said pin permanently fast- The front side of theclip B, between the ears C C, is made concave, as shown at a, and is alongitudinal recess, in which lies a fla-t curved spring, b, the lowerend whereof is held by the front heel of the clip, as shown.

E represents the thill, having the thill-iron Gr secured to it in any ofthe known and usual ways. On'the end of the thill-iron G is formed aneye or cylindrical extension, Gr', in which is a slot, d, extending fromthe center through a, so that it is impossible for the thills to be-Vcome disengaged while in this position'.

I have shown a rib on the cylindrical exten-l sion, and a portion, i,cut away each side thereof. This rib forms a smooth round surface forthe spring b to rest against; but It 1s not essential to the working ofthe device.

The spring b prevents allrattling, and assists in holding the thills inplace.

Having thus fully described my invention, what I claim as new, anddesire to secureby Letters Patent, is-

In a thill-coupling, the clip B, provided with ears G C and iiXed pin D,and formed with concave or seat a, having recess` for the spring b, incombination with the thill-iron G G, formed with slot d, and flatportion fi, and spring b, all constructed substantially as and for thepurpose herein set forth.

In testimony that I claim the foregoing as my own I afX my signature inpresence of two witnesses.

WILLIAM H. BRACE.
